It seems that nothing is out of the question or too absurd to consider when it comes to Trump. Until now he has managed to scatter and disarm his critics and survive their attacks and skepticism. But now it looks like the anti-Trump movement is starting to coalesce and Trump is giving it new fuel on a daily basis. There's no way that he can lose the nomination on the first ballot at the upcoming GOP convention unless the rules are changed. It's beginning to look like they may be in for an overhaul.
All the wonks say it's a long shot, but consider that the chairman of the convention rules committee is a Cruz delegate and the co-chair of the committee is a Trump delegate who was originally a Bush supporter. Add the tepid support of Paul Ryan and Trump's dismal performances lately, and it's now a plausible scenario for a revolt to take place.
There are a lot of problems with the dump-the-trump movement. There's not a lot of time to pull it off, major changes would have to be made to the convention rules, and not least, a replacement candidate has to be found. Then, of course, Trump would have to go quietly, or if not quietly, quickly so the second string candidate can appear instantly Presidential.
I don't see anyone with the necessary gravitas and broad respect within the party to take the mantle. For instance, I can't see it being any of the other primary contenders that he whupped. If the Party voters wanted one of them they would have already picked him/her (for politeness including Carly, but not really).
So, maybe Romney, but the Party faithful blame him for being so poor a candidate that he he lost in 2012 when many thought he should have won in a walk.
Who else? Nobody I can think of.
But going back to Trump going quietly, he really does have a following. I would bet that the same proportion of Republican voters would stay home if he wasn't their candidate as a different group of them will stay home if he is. Of course, if he runs as an outside candidate he doubles down on his own aggrieved candidate status and his ardent and loyal followers follow suit on their anger at being relegated to outsiders by their own party.
The bottom line is that the GOP is screwed if he is their candidate and just as screwed if he's not. On top of that, either way it goes the GOP has almost decertified itself as a legitimate party, so they may well lose both the Senate and the House in the fall.
Good riddance.
